Summary: The goal of this lab was to determine the number of Calories in a variety of different foods. The foods provided in this were a cheese puff, a pecan, and a cashew. My partner and I, however, were not able to test the cheese puff due to time constraints. We were able to determine number of Calories in our two foods by burning them over water and testing the temperature change of before and after the heating. This determines Calories as a Calorie is the amount of energy it takes to heat 1 gram 1 degree.
Questions:
#1: We measured a temperature change in the water.
#2: We measure the amount of energy gained by the water to determine the amount of energy released by the food
#3: It's absorbed by the air or the tin can.
#4: I was surprised that such small pieces of food could actually have an impact on the water and that they were able to raise the temperature that significantly.
